"The criminals gained access to our e-commerce stock room and made away with an undisclosed amount of jewellery. In the process of the robbery critical infrastructure was damaged, which resulted in the e-commerce store being closed until the infrastructure has been repaired," he said.

Downing said the e-commerce store was expected to be available for normal trading this week.

"The robbery is being investigated by the police. We apologise to our customers for the inconvenience caused and thank them for their patience," he said.
